Marathon Gas is home to a hidden gem of a restaurant called Frank Allen's, located inside the gas station. This spot provides a down home atmosphere where customers feel like family. It captures a small town, country experience that is hard to find in the tourist area, offering an incredible and affordable lunch or breakfast spot. The food receives high praise, with mentions of the best burger so far, amazing hotdogs like slaw dogs and nacho dogs, delicious crispy French fries, and mouth-watering onion rings. The breakfast is also noted as perfectly capturing a small town meal. The restaurant is very clean with great service, counteracting any concerns about a greasy or dirty gas station eatery. Orders are placed at a counter with seating available on old-fashioned stools or in booths. Beyond the food, the service is exceptional. The staff runs the business with a focus on the customer coming first, demonstrating helpfulness and kindness, such as assisting a stranded traveler with a vehicle repair. This combination of delicious, non-greasy food, a clean and friendly environment, and outstanding service makes Frank Allen's at Marathon Gas a regular stop and a new favorite for many visitors and locals alike.
